Abstract

This invention discloses a ceramic raw material flotation and cleaning device and its usage method, including a cleaning machine shell, inside which a second material pipe is installed. A support rod is fixed to one end of the side wall of the second material pipe, and the other end of the support rod is fixed to a buffer plate. A scraping mechanism is arranged above the buffer plate. The scraping mechanism includes a flotation plate, a third motor, and a sleeve plate. A connecting rod is sleeved on one side of the flotation plate, and the third motor is embedded inside the connecting rod. In this invention, the raw material is screened and buffered inside the feeding mechanism to prevent large materials from entering the second material pipe. The uniform rotation of the second feeding plate can adjust the speed of the raw material's downward movement, reducing the impact force during the downward movement of the raw material and improving the flotation effect. Multiple scrapers are added to increase the scraping force on the flotation plate, improving the scraping effect on mineral powder and reducing the residue of mineral powder on the flotation plate. Gears one and two realize the rotation of the second material pipe, enabling the scraping mechanism to rotate and move up and down on the second material pipe.

Description

Technical Field

[0001] This invention relates to the field of ceramic raw material flotation technology, specifically to a ceramic raw material flotation and purification device and its usage method. Background Technology

[0002] Flotation refers to the use of surfactants—foaming agents—that generate a large number of bubbles. When air is introduced into water or when air is introduced into the water due to agitation, the hydrophobic end of the surfactant is oriented towards the air bubble at the gas-liquid interface, while the hydrophilic end remains in the solution, forming bubbles. Through flotation, the bubbles can carry away the specified mineral powder, achieving the purpose of mineral beneficiation.

[0003] In the prior art, such as the Chinese patent CN115318451A entitled "A Ceramic Raw Material Flotation and Refinement Device", the flotation machine body includes a flotation cell, an air conveying pipe disposed in the flotation cell, and a discharge pipe disposed at the end of the flotation cell away from the air conveying pipe; a standard ring is disposed in the flotation cell, the discharge pipe is disposed at the upper end of the standard ring, the air conveying pipe is disposed at the lower end of the standard ring, and a support rod is disposed in the flotation cell; and a flotation assembly includes a flotation plate rotatably connected to the upper end of the support rod, a screen plate disposed on the flotation plate, and a raw material conveying pipe disposed on the support rod, the lower end of the raw material conveying pipe extending outward from the support rod, and the air conveying pipe conveying air to cause the flotation plate to rotate.

[0004] However, in the existing technology, the scraper scrapes down the bottom mineral powder with the aid of the reciprocating rotating flotation plate and scraper to collect the mineral powder. The ceramic raw material falls directly into the flotation machine and comes into contact with the water. When the flow rate of the raw material is too fast, the impact force is large, and excess impurities quickly escape and float on the water surface, affecting the flotation effect. Moreover, after the mineral powder is collected on the flotation plate, the contact force between the scraper and the flotation plate is small, and the scraping effect of the mineral powder is not ideal. Summary of the Invention

[0005] The purpose of this invention is to provide a ceramic raw material flotation and refining device and its usage method, in order to solve the problems mentioned in the prior art mentioned above, where the impact force is large when the raw material flow rate is too fast, and excess impurities quickly escape and float on the water surface, affecting the flotation effect. Furthermore, after the mineral powder is collected on the flotation plate, the contact force between the scraper and the flotation plate is small, resulting in an unsatisfactory scraping effect on the mineral powder.

On the second feed pipe, a scraper is attached to the top of the flotation plate, and a sleeve plate is fitted onto the top of the scraper. A connecting ring is fixed to one end of the sleeve plate, and the connecting ring is fitted onto the second feed pipe. A material distribution mechanism is provided above the scraping mechanism. The material distribution mechanism includes a baffle ring, a first feeding plate, and a collection hopper. The baffle ring is fixed to the inner wall of the material distribution hopper, and a second feeding plate is fixed to the bottom of the baffle ring. The bottom of the second feeding plate overlaps with the first feeding plate. The bottom of the first feeding plate is connected to the output shaft of the second motor, and the second motor is fixed to the inner wall of the collection hopper.

[0007] Preferably, a guide block is fixedly connected to the top of the second feeding plate, the guide block is located below the first material tube, the first material tube passes through the auxiliary cylinder, one end of the connecting pipe is fixedly connected to the side wall of the auxiliary cylinder, and the other end of the connecting pipe is fixedly connected to the top of the sleeve plate.

[0008] Preferably, an airbag is installed between the top of the inner cavity of the sleeve plate and the scraper, the sleeve plate and the scraper are slidably connected, one end of the sleeve plate is sleeved on the second material tube, the second material tube is threaded, and the second material tube and the collar are connected by threads.

[0009] Preferably, the second feeding plate and the first feeding plate are respectively provided with a second through hole and a first through hole, the first through hole being located below the second through hole, and the first feeding plate being rotatably connected to the inner wall of the distributing hopper.

[0010] Preferably, the top of the second material pipe penetrates the bottom side wall of the distribution hopper, and a second gear is fixedly connected to the top of the second material pipe, and the second gear is meshed with the first gear.

[0011] Preferably, the gear is fitted onto the inner wall of the distribution hopper, and one side of the gear is connected to the output shaft of the motor, and the motor is fixedly connected to the distribution hopper.

[0012] Preferably, an extension cylinder is fixedly connected to the top of the hopper, the extension cylinder is sleeved outside the material pipe, and the material pipe is located above the through hole.

[0013] Preferably, a fixing block is embedded inside the flotation plate, the fixing block is connected to the output shaft of the motor, and the flotation plate is rotatably connected to the connecting rod.

[0014] Preferably, a collecting hopper is attached to the bottom of the feeding plate, the collecting hopper is fixed to the inner wall of the distributing hopper, and the collecting hopper is located above the material pipe.

[0015] Preferably, the steps of the usage method are as follows:

[0016] S1. The raw material enters the distribution hopper through the feed pipe one, falls onto the feed plate two after passing through the guide block, and a filter screen is installed on the inner wall of the through hole two. The motor two drives the feed plate one to rotate, so that the through hole one and the through hole two coincide. At this time, the material moves down and enters the feed pipe two from the bottom of the collection hopper.

[0017] S2. After being buffered by the buffer plate, the material enters the bottom of the inner cavity of the separator. The material comes into contact with the liquid inside the separator. The hydrophobic end of the surfactant inside the separator is oriented towards the air bubble at the gas-liquid interface, while the hydrophilic end remains in the solution, forming bubbles. The designated mineral powder is carried away by the flotation bubbles. Motor 1 drives gear 1 to rotate. Gear 1 meshes with gear 2 to drive material tube 2 to rotate.

[0018] S3. At this time, the collar drives the scraping mechanism to move upward. A limit rod is fixed to the top of the collar. The top of the limit rod overlaps with the connecting ring. The motor three inside the connecting rod drives the flotation plate to rotate, so that the flotation plate is in a horizontal state. A bearing is installed between the connecting ring and the material tube two, so that it can remain stationary while the material tube two rotates, so that the flotation plate can contact the scraper when it moves upward.

[0019] S4. Use external equipment to introduce air into the auxiliary cylinder. The air can be discharged from the auxiliary cylinder and enter the liquid. Excess gas enters the sleeve through the connecting pipe. Adjust the air pressure inside the air bag to drive the scraper to move down and contact the top of the flotation plate. While the flotation plate is rotating, the scraper removes the mineral powder collected on the top of the flotation plate.

[0020] S5. After scraping is completed, the second feed tube rotates in the opposite direction, so that the scraping mechanism moves downward. The flotation plate can be flipped in the opposite direction to a vertical state. The scraping mechanism rotates on the second feed tube, and the flotation plate contacts the air bubbles to assist in flotation. Excess raw materials can be discharged from the bottom of the cleaner casing.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, the raw materials are screened and buffered inside the material distribution mechanism to prevent large materials from entering the material pipe 2. The uniform rotation of the material discharge plate 2 can adjust the speed of the raw material's downward movement, ensuring that the raw material is in full contact with the liquid, reducing the impact force when the raw material moves downward, reducing the floating of impurities on the liquid surface, and improving the flotation effect.

[0023] 2. In this invention, the height of the scraper is adjusted by utilizing the air pressure change inside the sleeve plate, thereby increasing the scraping force of multiple scrapers on the flotation plate, improving the scraping effect on mineral powder, reducing the residue of mineral powder on the flotation plate, and facilitating the collection of mineral powder inside the shell of the cleaning machine.

[0024] 3. In this invention, the combined use of gear one and gear two ensures the feeding of raw materials while enabling the rotation of material pipe two. This allows for the rotation and lifting adjustment of the scraping mechanism on material pipe two, facilitating contact between the flotation plate and air bubbles, and aiding in the rapid collection of mineral powder.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0035] Reference Figure 1-7 As shown: A ceramic raw material flotation and refining device includes a refining machine shell 1. A material pipe 76 is installed inside the refining machine shell 1. One end of a support rod 81 is fixed to the side wall of the material pipe 76. The other end of the support rod 81 is fixed to a buffer plate 8. A scraping mechanism 9 is provided above the buffer plate 8. The scraping mechanism 9 includes a flotation plate 91, a motor 913, and a sleeve plate 93. A connecting rod 911 is sleeved on one side of the flotation plate 91. The motor 913 is embedded inside the connecting rod 911. One end of the motor 913 is fixed to a collar, which is sleeved on the material pipe 76. A scraper 92 overlaps the top of the flotation plate 91. A sleeve plate 93 is sleeved on the top of the scraper 92. A connecting ring is fixed to one end of the sleeve plate 93, which is sleeved on the material pipe 76. The motor 913 inside the flotation plate 91 can drive the rotation adjustment of the flotation plate 91 to change the horizontal or vertical state of the flotation plate 91.

[0036] Above the scraping mechanism 9, a material distribution mechanism 7 is provided. The material distribution mechanism 7 includes a baffle ring 72, a first discharge plate 73, and a collecting hopper 74. The baffle ring 72 is fixed to the inner wall of the distributing hopper 71. A second discharge plate 78 is fixed to the bottom of the baffle ring 72. The bottom of the second discharge plate 78 overlaps with the first discharge plate 73. The bottom of the first discharge plate 73 is connected to the output shaft of the second motor 79. The second motor 79 is fixed to the inner wall of the collecting hopper 74. A guide block 77 is fixed to the top of the second discharge plate 78. The guide block 77 is located below the first material pipe 3. The first material pipe 3 passes through the auxiliary cylinder 4. The side wall of the auxiliary cylinder 4... One end of the connecting pipe 5 is fixedly connected, and the other end of the connecting pipe 5 is fixedly connected to the top of the sleeve 93; an airbag is installed between the top of the inner cavity of the sleeve 93 and the scraper 92; the sleeve 93 and the scraper 92 are slidably connected; one end of the sleeve 93 is sleeved on the second material pipe 76; the second material pipe 76 is threaded; the second material pipe 76 is threadedly connected to the collar; the second material plate 78 and the first material plate 73 are respectively provided with a second through hole 781 and a first through hole 731; the first through hole 731 is located below the second through hole 781; the first material plate 73 is rotatably connected to the inner wall of the distributing hopper 71.

[0037] The baffle ring 72 can limit the downward movement range of the material, preventing the material from moving outside the top of the feed plate 2 78, and smoothly moving the material from the feed plate 2 78 into the through hole 731 on the feed plate 1 73. After the material moves down, it can enter the feed tube 2 76. By rotating the feed plate 1 73, the material can be fed at intervals, slowing down the downward movement speed of the material and preventing excessive material from being concentrated and impacting the liquid inside the separator shell 1. Excess material will float to the surface of the liquid and affect the flotation effect of the entire device.

[0038] The top of material pipe 2 76 penetrates the bottom side wall of the distribution hopper 71. Gear 2 75 is fixedly connected to the top of material pipe 2 76, meshing with gear 1 61. Gear 1 61 drives the rotation of material pipe 2 76. Gear 1 61 is sleeved on the inner wall of the distribution hopper 71, and one side of gear 1 61 is connected to the output shaft of motor 1 6. Motor 1 6 is fixedly connected to the distribution hopper 71, facilitating the rotation adjustment of gear 1 61 by motor 1 6, controlling the forward and reverse rotation of gear 1 61, and thus adjusting the rotation direction of material pipe 2 76. An extension cylinder 2 is fixedly connected to the top of the distribution hopper 71, sleeved outside material pipe 1 3. Material pipe 1 3 is located at through hole 2 7. Above 81, the feed pipe 1 3 can guide the movement of ceramic raw materials, making it easier for the raw materials to reach the feed plate 2 78; the flotation plate 91 has a fixed block 912 embedded inside, which is connected to the output shaft of the motor 3 913. The flotation plate 91 is rotatably connected to the connecting rod 911, which facilitates the position adjustment of the flotation plate 91. After the flotation plate 91 rotates, it can contact the scraper 92 to achieve rapid scraping of mineral powder; the bottom of the feed plate 1 73 is connected to the collection hopper 74, which is fixed to the inner wall of the distribution hopper 71 and is located above the feed pipe 2 76. The collection hopper 74 can collect the filtered ceramic raw materials and send the raw materials into the feed pipe 2 76.

[0039] The usage steps are as follows:

[0040] Step 1: The raw material enters the distribution hopper 71 through the feed pipe 3. The motor 2 79 drives the feed plate 1 73 to rotate, so that the through hole 1 731 and the through hole 2 781 coincide. The material moves down and enters the feed pipe 2 76 from the bottom of the collection hopper 74.

[0041] Step 2: The material comes into contact with the liquid inside the shell 1 of the separator. The hydrophobic end of the surfactant inside the shell 1 of the separator is oriented towards the air bubble at the gas-liquid interface, while the hydrophilic end remains in the solution, forming bubbles. The specified mineral powder is carried away by the flotation bubbles.

[0042] Step 3: The motor 913 inside the connecting rod 911 drives the flotation plate 91 to rotate, so that the flotation plate 91 is in a horizontal state. A bearing is installed between the connecting ring and the feed tube 76, which can keep it stationary while the feed tube 76 rotates, so that the flotation plate 91 can contact the scraper 92 when it moves upward.

[0043] Step 4: Use an external air pump to introduce air into the auxiliary cylinder 4. The air can be discharged from the auxiliary cylinder 4 and enter the liquid. Excess gas enters the sleeve 93 through the connecting pipe 5. Adjust the air pressure inside the air bag to drive the scraper 92 to move down and contact the top of the flotation plate 91. The collar drives the scraping mechanism 9 to rotate. While the flotation plate 91 is rotating, the scraper 92 scrapes the mineral powder collected on the top of the flotation plate 91.

[0044] Step 5: When the feed tube 2 76 rotates in the reverse direction, the scraping mechanism 9 moves downward, and the flotation plate 91 can be flipped in the reverse direction to a vertical state. The scraping mechanism 9 rotates on the feed tube 2 76, and the flotation plate 91 comes into contact with the air bubbles to assist in flotation. Excess raw materials can be discharged from the bottom of the shell 1 of the cleaning machine.

[0045] The working principle and usage of this device are as follows: First, the raw material enters the distribution hopper 71 through the feed pipe 3. It falls onto the discharge plate 78 after passing through the guide block 77. A filter screen is installed on the inner wall of the through hole 781. The motor 79 drives the discharge plate 73 to rotate, so that the through hole 731 and the through hole 781 coincide. At this time, the material moves down from the bottom of the collection hopper 74 into the feed pipe 76. After being buffered by the buffer plate 8, it enters the bottom of the inner cavity of the separator shell 1.

[0046] Next, the material comes into contact with the liquid inside the shell 1 of the separator. The hydrophobic end of the surfactant inside the shell 1 is oriented towards the air bubble at the gas-liquid interface, while the hydrophilic end remains in the solution, forming bubbles. The designated mineral powder is carried away by the flotation bubbles. Motor 6 drives gear 61 to rotate, and gear 61 meshes with gear 75 to drive the feed tube 76 to rotate.

[0047] Then, the collar drives the scraping mechanism 9 to move upward. A limit rod is fixed to the top of the collar, and the top of the limit rod overlaps with the connecting ring. The motor 913 inside the connecting rod 911 drives the flotation plate 91 to rotate, so that the flotation plate 91 is in a horizontal state. A bearing is installed between the connecting ring and the material tube 76, which can remain stationary while the material tube 76 rotates, so that the flotation plate 91 contacts the scraper 92 when it moves upward.

[0048] Next, air is introduced into the auxiliary cylinder 4 using an external device. The air can be discharged from the auxiliary cylinder 4 and enter the liquid. Excess gas enters the sleeve 93 through the connecting pipe 5. The air pressure inside the air bag is adjusted, which drives the scraper 92 to move down and contact the top of the flotation plate 91. The collar drives the scraping mechanism 9 to rotate. While the flotation plate 91 is rotating, the scraper 92 scrapes the mineral powder collected on the top of the flotation plate 91.

[0049] Finally, after scraping is completed, the second feed tube 76 rotates in the opposite direction, causing the scraping mechanism 9 to move downward. The flotation plate 91 can be flipped in the opposite direction to a vertical state. The scraping mechanism 9 rotates on the second feed tube 76, and the flotation plate 91 comes into contact with the air bubbles to assist in flotation. Excess raw materials can be discharged from the bottom of the cleaner casing 1.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
